Product Description

QA1’s spherical bearings are available in a wide variety of sizes, styles and materials with or without PTFE liners. Custom sizes and materials available upon request.

SLB Endura Series Spherical Bearings
For the ultimate in performance spherical bearings, look no further than QA1’s SLB Endura Series spherical bearings. SLB Series spherical bearings are completely self-sealing and self-lubricating because of their Nylon/PTFE injection molded race that keeps dirt and debris out. This design results in metal to metal support for heavy shock loads and smooth operation for low and moderate loads.

COM & COM-T Commercial Series Spherical Bearings
For an economical traditional spherical bearing, QA1’s COM and COM-T Series is the perfect choice. Each bearing is made from chromoly steel with an optional self-lubricating PTFE liner.

GEZ Series Fractured Race Spherical Bearings
Ideally suited for high wear and increased load applications in industrial markets, QA1’s GEZ Series fractured race spherical bearings are manufactured using 52100 bearing steel. Because of the strength of the steel, the race cannot be molded around the ball and therefore is fractured slightly to allow the ball to be inserted. The hardened and ground surfaces allow for full ball to race conformity, resulting in reduced wear, smooth operation and less localized stress.
